TYPE-WRITING :MACHILH'E.

mmmmmm Application fild May 3, 193.5.

To-all whom it may concern I Be it known that we, EDWARD B. Hess and Laws C. MYERS, of the borough of Brooklyn, county of Kings, and State of New York; citizens of the United States of America, have jointly invented certain new and useful Improvements in T ype-Writing .Machines, vof which the following is a specification. I

The improvements in typewriting machines of this invention relate to means for protecting the pivotal connections of the type actuating mechanism and also for affording means for centralizing the rocking ends of the key levers withtheir bearing supports whereby the bearing rod or shaft may be readily and freely applied in assembling the key levers. It also includes an improved front link support and other features of construction hereafter fully described, reference being had to the accompanying drawings, which illustrate the improvements applied to the Royal typewriter.

Figure 1 is a central section of the machine, looking toward the left: Fig. 2, an enlarged view of the combined dust guard or shed and centralizing means for the rocking ends'of the key' levers: Fig. 3, illustrates a portion of the bearing rod of the key levers.

The parts of a Royal typewriter shown to illustrate the application of the features of this invention thereto may be briefly stated as consisting of the main frame 6, carriage 7, carriage shift 8, platen 9, spacing lever 10, paper pan 11, type bars 12,type head rest 13, universal bar 1%, ribbon spool cover or housing 15 and top casing and dust guard 16.

The key levers 17 are each connected by a vertical link 18 to a front link 19 connectedat the rear end to type bar 12 by a link 20. To link 20.i's secured a bar orv link 21 having the rear end bent to engage the universal bar l t. On each universal bar connecting link 21 is a spring 22 whose rear- Speoification of Letters Patent.

ation, difiiculty often occurring in properly for alining the holes of the key levers with the holes of the supporting comb 25, as shown at Fig. 2. From this "iew it will be seen that the bearing shaft or rod 27 may be readily slipped through the holes, the key levers being merely set in the spaces of the comb support, and to facilitate the in sertion of the rod 27 its end may be pointed, as at 28. This plate 26 has a dual function. It acts as an alining means for the key levers and also as .a dust cover for the working bearings of said levers, the upper horizontal part 29 extending forward over the levers sufficiently to protect the bearings from any dust or dirt that may fall from or between the type bars.

The supporting bar 30 carrying the bearings of the front links 19 has a flange 31 at its inner or rear side to protect the bearings from dirt from the inner part of the machine, the links being bent, as shown, to extend down under the flange 31 and beneath cleaning the type. Its front part 38 extends downwardly to the key board, acting as a protecting apronfor the front of,the machine.

The annexed drawings show certain devices at the rear end of the machine for adjusting the springs which surround the links which connect the universal bar with the type barlinks. Such subject matter is not claimed herein but is claimed in our appli-- cation for- Patent No. 91,060, filed April 14,

We claim:

1. In a typewriting machine, key levers, a bearing bar for the rear ends of the key levers, an alining plate extending upwardly mosses in rear of the bearing bar and having its to aline their holes with the bearing-holes of the bearing bar and a bearing rod or shaft having a pointed end by which it may be readily inserted through the holes of the levers and holes of the bearing bar.

8. Ina typewriting machine, key levers, a. bearing bar to which the rear ends of the key levers are pivotally connected, front links of link systems for operating the type bars, vertical links connecting the key levers to the front links, and a supporting bar provided with bearings for the front links and having at its rear side a downwardly extending flange, said front links being formed with a bend to extend under said flange.

4-. In a'typewriting machine, key levers, a earing bar to which the rear ends of the key levers are pivotally connected, front links of link systems for operating the type bars, vertical links"connecting the'key levers to the front links, a supporting bar provided With bearings for the front links and having its upper side inclined downwardly toward the front edge, and a dust guard formed to seat on the upper side'of the front link supporting bar and to extend downwardly to the key levers in front of themachine.

5.111 a typewriting machine, key levers, a bearing bar to which the rear ends of the key levers are pivot ally connected, front links of link systems for operating the-type bars, vertical links connecting the key levers to the front links; a supporting bar provided with bearings for the front links and having its upper side inclined downwardly toward the front edge and a, dust guard formedjto seat on the upper side. of the front link supporting bar and to extend downwardly to the key levers in front of the machine, the upper part of said dust guard being shaped to conform to the curvature of the face line of the type heads.

6. In a typewriting machine, key levers, a bearing bar to which the rear-ends of the key levers are pivotally connected, front links of link systems for operating the type bars, vertical links connecting the key levers to the front links, a supporting bar provided with bearings for the front links and having at its rear side a downwardly extending flange arid its upper side inclined downwardly toward the front edge and a dust guard secured to said bar and shaped to conform to the curvature of the face line of type heads.

7, In a typewriting machine, key levers, having their rear ends perfo'ated and rounded, a bearing bar to which the rear ends of the key levers are pivotally con nected and a guide plate attached to the bearing bar and extending upwardly therefrom in rear of the levers and over the top of their rounded rear ends for controlling the ends ofthe key levers as the parts are being assembled to sctthc holes in the levers in alinement with the bearing holes of the bar to facilitate the insertion of a hearing rod or shaft.

8. In a typewriting machine, key levers, a bearing bar to which the rear ends of the key levers are pivotally connected, front links of link systems for oymrating the type bars, vertical links connecting the key le-- vers to the front links. a supporting bar provided with bearings for the front links and having at its mat-side a downwardly extending flange and its upper side in: clined downwardly toward the front edge, a dust guard secured to said bar and shaped to conform to the curvature of the face line of type heads, and a guard plate secured to the key lever hearing bar and extending around the ends of the key levers to protect their bearings from dust.

In testimony whereof, we have hereunto subscribed our names.
